Abstract
Synopsis: During the period of glacial retreat that followed the Loch Lomond Advance maximum, a sequence of ice-dammed lakes formed in the Loch Tulla area of East Argyll, Scotland. The main evidence for this lake sequence consists of abandoned shorelines at altitudes of 332 m, 323 m, 319 m, 315 m and 248 m above sea level. These shorelines are restricted to the eastern part of the Tulla basin, and their altitudes correspond with these of local outlet cols. It is considered that the lakes formed on the eastern margin of a mass of downwasting glacier ice and did not occupy the entire basin, as has previously been suggested. The lowest lake probably drained englacially through the downwasting ice mass.Keywords
